The uncomfortable truth

Your dog’s water bowl is dirtier than you think

Still water grows biofilm, a slimy film of bacteria built from saliva, food bits and dust. In NSF International’s household germ study, pet bowls ranked among the germiest items in the home.

Rinse it in the morning and the film is building again by the afternoon. Your dog laps through it with every single drink.

  • 4-stage filtration catches hair, dust and debris before every sip
  • A fresh, filtered stream every time your dog comes to drink
  • 304 stainless steel is far easier to keep clean than scratched plastic

Drag to compare

What’s happening in the water your dog drinks

01

Bacteria & Biofilm Buildup

Still water becomes a breeding ground within hours. That slimy film inside the bowl? A bacteria layer your dog laps up with every drink.

02

Slobber, Crumbs & Hair

Every drink leaves saliva and kibble bits behind, and hair and dust drift in. In a still bowl, all of it just sits there.

03

Stale By Lunch

Your dog’s nose is far more sensitive than yours. The bowl you filled at 7 a.m. smells flat and stale to them by midday.

04

Warm, Flat, Ignored

Warm still water holds less oxygen and tastes worse. KaiShine starts a fresh, filtered stream every time your dog walks up.

Why KaiShine beats the bowl

Rule of thumb: dogs drink about 1 oz of water per lb of body weight a day. Heat, exercise and dry food mean more. Whatever the size, refill with fresh water at least once a week.

3.2L TankRefill every few days to a week

108 oz of water. Small dogs go about a week between refills, medium dogs a few days, and the round window shows the level at a glance.

Smart Motion SensorFlows when your dog walks up

Sensor mode starts the stream when your dog is within about 3 ft, which saves battery. Want more flow? Timed mode runs short bursts and continuous runs a steady stream (both use more battery).

No cord to chew

No cord. Nothing to chew, trip over or unplug.

Plug-in fountains trail a power cord across the floor, right at puppy height. KaiShine runs on a built-in battery, so there is simply no cord at all.

  • Nothing for a teething puppy to chew
  • No cord to trip over or knock loose
  • Up to 45 days per charge, USB-C recharge

Easy to keep clean

No slimy bowl. No plastic smell.

Scratched plastic holds on to the film your dog can smell long before you can see it. Smooth 304 stainless steel rinses clean in a minute.

  • Rinse the steel basin when you top it up
  • Swap the filter in 10 seconds, about every 2 months
  • Refills can arrive on their own with the One-Year Plan

Got a cat too? They can share.

KaiShine started life as a fountain for picky cats, so the stream is gentle and quiet enough for both. One fountain, one refill routine.

  • A gentle, quiet stream for cats and small dogs
  • The Two-Year Plan’s 12 filters suit multi-pet homes
  • With two pets, plan on topping it up more often

Questions dog parents actually ask

Is it big enough for my dog?
KaiShine holds 3.2 liters (108 oz) and is made for small and medium dogs. Dogs drink about 1 oz of water per lb of body weight a day, so a full tank lasts a 15 lb dog about a week and a 30 lb dog about 3–4 days. Over 50 lb it still works, but you’ll be refilling every day or two.
Will my dog actually use it?
Most dogs are curious about moving water. Put it where your dog already hangs out, away from the food bowl, and give them a day or two. If yours won’t use it within 30 days, we refund everything.
Can my dog knock it over or chew it?
It’s a solid steel basin with a flat base, and there’s no cord to chew. For very playful dogs, set it against a wall. The fountain itself isn’t a chew toy, and chewing damage isn’t covered by the warranty.
How often do I clean and refill it?
Refill every few days to once a week depending on your dog’s size, rinse the steel when you do, and swap the filter cartridge in ten seconds, about every 2 months. Wash it by hand; it isn’t dishwasher safe.
How long does the battery last?
Up to 45 days per charge in sensor mode (4200 mAh), less in timed or continuous mode. Recharge it with the included USB-C cable and any USB phone charger — no dock, no proprietary plug.
Does it come with a wall plug?
It comes with a USB-C charging cable, not a wall adapter. Any USB phone charger or laptop USB port works.
Is it really quiet?
Under 40 dB — about as quiet as a library — and in sensor mode the stream only runs when your dog walks up, so nothing hums all night.
Can my cat use it too?
Yes. KaiShine started as a fountain for picky cats, so the stream suits both. With two pets, plan on topping it up more often; the Two-Year Plan’s 12 filters are the easy choice.
I have two dogs. Will it keep up?
Yes, you’ll just refill it more often. Two 20 lb dogs drink about 40 oz a day, so a full tank lasts them about 2–3 days. Give the steel a rinse each time you top it up.
When will it arrive?
Orders are handed to the carrier within 2–4 business days, and US delivery typically takes 7–14 business days from the day you order. Shipping is free and tracked. You get a tracking link by email as soon as the carrier scans your package.
What if it stops working?
The fountain has a 12-month limited warranty against manufacturing defects, counted from delivery. Email contactsupport@kaishinepet.com with your order number and a line about what happened, and we’ll sort it out. The warranty doesn’t cover drops, chewing, dishwashers, descaling chemicals or running the pump dry.
How do returns work?
You have 30 days from delivery, and a used fountain is fine. Email contactsupport@kaishinepet.com with your order number. We reply within one business day with instructions and, where a return is needed, a prepaid label. Once the carrier scans it, we refund you in full within 2 business days.

Give your dog water worth drinking.

A stream they love to lap, steel that rinses clean, and refills that show up on their own.
